This is a premium feature and requires the Standard plan or above.
You can show delivery estimates on the Order Status page using our extension available in the theme editor.
After adding the extension to your theme you can check order delivery estimates in the "Orders" section of the app.
Note that this only contains information for orders that have come in since you installed Arrives By.
You can manually edit any of the delivery estimates due to inventory changes, shipping delays, holidays, etc.
